HOT-WATER HEATER.

Specification of Letters Patent.

Patented Got. 14,1913.

Application filed January 19, 1912. Serial No. 672,118.

To all whom it may concern:

Be it known that I BENJAMIN G. DOLL 7 a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Hot- VVater Heaters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a hot water heater for buildings, and relates more particularly to means whereby each radiator or heating coil is controlled and supplied from the heater in a separate manner.

The oractice has been to use a common boiler for the entire system of distribution, so that if the boiler fails to perform its work, the entire heating system was thrown out and the cutting out of one radiator to the relief of the other was an impossibility, the result being that if a flow was to one floor and radiator, the other floors and radi- 'ators would not receive the full supply of the hot water. The object of the invention is to provide a heater that shall be cheap, durable, cfiicient, and so constructed that renewals of parts may be readily effected.

Another object of the invention is to provide means whereby the water to supply each radiator is heated in a separate man- Still another object is to provide a heater that will supply hot water to a radiator or coil situated on a lower plane than that of the heater, as in the case of a sub-cellar.

Vith these and other objects in view, my invention consists in certain construction and combination of parts as will hereinafter be described and claimed in the annexed specification, and illustrated in the accompanying drawings which form a part of this application, and in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my invention as shown, that I do not confine myself to the exact design, as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention.

In the drawings :-Figure 1, is a partial View of a heater shown in perspective, with the side cut away to expose my device. Fig. 2, is a vertical sectional view of the same. Fig. 3, is a horizontal sectional view of one of the diaphragms. Fig. 4, is a cross-sectional view of the main water chamber.

Referring to the drawings z l, indicates the usual walls of a furnace forming a combustion chamber 2, within tie lower part of which are the grates 3. Within said con bustion chamber 2, and surrounding three sides of the grate 3, is placed a main water -locating chamber 4, composed of a casting 7, which is U-shaped in crosssection and formed with a flange 5, to which are secured the fire wall plates 6. The upper surface of said casting 7, is provided with a series of vertical pipes 8, communicating with the chamber 4, therein; each of said vertical pipes 8, being in two parts and connected by a union 9.

Mounted in a vertical transverse position within the chamber 4, and supported upon the upper ends of the pipes 8, to which they are secured by the fitting 10, are the water heating diaphragms which are composed of the parts 11, and 12; the part 11, being provided with a flange 18, to which the part 12, is secured, thus forming a compartment 14, capable of holding a thin sheet of water. The upper end of said diaphragm chamber 14, is connected to a flow-pipe 15, which supplies an individual radiator or coil 16, the return pipe 17, from which enters a header 18, which is connected to the rear end of the casting 7 thus returning the water to the main chamber 4. It will thus be seen that there is one diaphragm provided for each radiator or coil to which it is connected by an individual flow pipe, and as the dia phragm is placed in the combustion chamber directly over the fire and as the water passing therethrough is in a thin sheet, it is heated in an almost instantaneous man ner and rendered very hot with a small amount of fire, thus sending it to a coil or radiator in any part of the building, either above or below the plane of the heater; and furthermore, any radiator or coil may be cut out without affecting the remaining ones.

It is, of course, understood that the valves 19, which control the coils are so constructed as to provide a sufficient leak to prevent trouble caused by steam forming in the diaphragm.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is In a hot water heater of the class deple of Water heating chambers mounted in ently connected to said Water heating oom- 10 partment.

In testimony whereof I affix my signature in presence of two Witnesses.
